Application filed March 23,

To all whom it may concern: 7

Be it known that I, WILLIAM A. WHITE, a citizen of the United'States, residing at Palmetto Blufi',jin the county of Beaufort and State ofSouth Carolina, have invented certain new and useful Improvements in Lamp-Chimney Cleaners, of which the following is a specification, reference being had to the accompanying drawings. 7

This invention relates -to an improved lamp chimney cleaner and has for its primary object to provide a simple and efficient means whereby the interior of a lam chimney may be quickly and thoroughly cleaned.

It is another and more particular object of ,the invention to provide a device for the ove purpose having a plurality of resilient metal straps upon which the cloth,

paper or other cleaning material is adapted to be engaged, and means for expanding or bowing said straps in an; outward direction to engage the material with the wall of the lamp chimney as therein.

' It is a further the device is revolved or removed as a whole being relatively simple in its construction, strong and durable, and capa-. ble of manufacture at relativelysmall cost.

With the above and other objects in view the inventionconsists in .theimproved comoanation, construction, and relative arrange-,; ment of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate the corresponding parts throughout the several views, and wherein:

Figure 1 is a longitudinal section through a lamp chimney showing my improved cleaning device operatively engaged therein;

Fig. 2 is a side elevation of the device in its normal condition removed from the chimney;

Fig. 3 is a section taken on the line 3-3 of Fig. 2; and

Fig. 4 is a section taken on the line H of Fig. 1.

Referring in detail to the drawing, 5 designates a cylindrical rod, preferably though not necessarily of wood, said rod being Specifieation of Letters Patent. 7

diametrically"enlarged at one of its endsas at 6. 'Upon the rod 5, a, second tubular rod 7 is loosely engaged for longitudinal movement, said latter .rod also having an enlarged end portion .8.

each other at one of their ends, said straps being disposed in spaced relation around the rod 7 and the enlarged end of the rod 5.

ofthe straps 9 are secured to the enlargement (iof'the rod 5 by means ofa metal cap 10 which is engaged over said end'of the rod and the terminals of the straps and securely fixed to the rod by means of suitable fastening'elements in dicated at 11. Thejopposite ends of'the metal straps 9 are secured upon the periphof the rod 7 by means of the metal band 12 e e I around the end of said rod and overlying the metalstraps; This hand is fixed to the end of the rod by means of fastening elements 13. i

Beyond the end 8 of the disk 14 also preferably of wood is loosely engaged on the rod 5. An angular metal bracket member l5'is fixed to this disk, one arm of said bracket member extending in parallel relation to the rod 5 adjacent to the opening in the disk. This bracket armis provided in one edge with a notch or recess rod 7 a plate or 16." A radially projecting pin orstud-fl'? fixed in the rod 5 is adapted for engagement entl a ear. This in al diseh gag ment of the disk of the rod 5.

In. the operation of the device, assuming that the parts are in their normal positions seen in Fig. 2,. the device is. inserted through the neck of the lamp chimney indicated at C until the edge of the chimney neck is engaged against the plate or disk 14. The enlarged end of the rod 5 projects slightly beyond the opposite end of the chimney. It is of course understood that soaked paper, cloth strips or other material upon which a suitable cleansing agent has been applied, is first wrapped around the resilient metal straps 9. The operator while holding the disk 14 with one hand, with the other hand pushes inwardly against the end of the rod 5 thereby bowing or expanding the metal straps 9 outwardly and causing the paper or cloth to contact with the inner so prevents the 14 from the end,

surface of the bulged or curved portion of the chimney wall. T he rod 5 is then turned in the proper direction to engage the pin or stud 17 in the notch 16 of the bracketmember, whereby the rod 5 will be securely held against reverse longitudinal movement and the straps 9 maintained in their bowed or expanded condition. The disk 1% is now grasped by the operator and the device turned or revolved within the lamp chimney, In this manner, it will be apparent that all parts of the inner surface of the lamp chimney will be en aged by the cleaning material and thoroughly cleaned. In order to remove the device, it is only necessary to first turn the rod 5 in the proper direction while holding the disk ll so as to disengage the pin 17 from the bracket number. The resilient metal straps will then return to their normal condition so that they can be withdrawn through the neck of the chimney. A dry cloth or paper is then applied upon the metal straps, and after rinsing the inner surface of the lamp chimney, the device is then engaged therein as above stated and turned to dry the surface of the chimney wall.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have devised a very simple, serviceable and highly etlicient device whereby the interior surfaces of lamp chimneys can be easily, quickly and thoroughly cleaned. The device can be readily engaged within the chimney or removed therefrom without danger of breaking or chipping the chimney. Any desired number of the resilient metal straps may be employed, and while these straps are preferably of metal, they can also be made of various other materials and may be either fiat or round as desired. The several other elements of my improved lamp chimne cleaner are also susceptible of many modifications in the form, proportion and relative arrangement thereof and I therefore reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus I claim is 1. A lamp chimney cleaner including a rod having an enlarged'encl portion, a tube loosely engaged upon the rod, a plurality of eXpansible elements ends to the enlarged'end of the rod'and to the relatively remote end of the tube, said enlarged end of the rod limiting the expansion of said elements, and means for locking the rod and tube against return movement to their normal positions.

2. A lamp chimney cleaner including a rod having an enlarged end portion, a tube loosely engaged upon the rod, a plurality of expansible elements fixed at one of their endsto the enlarged end of the rod and to the relatively remote end of the tube, said enlarged end of the rod limiting the expansion of said elements, a disk loosely engaged upon the rod and of greater diameter than the tube, said disk affording a seat for one end of a lamp chimney, and coacting means on said disk and the rod to lock said disk and rod against movement with respect to the tube and retain said elements in expanded condition.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
